HEATING arrannrusa Application filed November 5,1920. Serial no. 422,079.

To all whom it may concern Be it known that I, Rnxrono O. .ANDER- son, a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in a Heating Apparatus, or" which the following is a specification.

This invention relates 'to new and useful improvements in a heating apparatus,

One object of the invention is to provide an apparatus by means of which heat may be readily conveyed from one fluid to an other without bringing the two fluids into direct contact.

With the above and other objects in view,

the invention has particular relation to certain novel features. of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, Whereim- Figure 1 shows a side view of the device, partially in section, and

Figure 2 shows an end view, shown partially in section, and with the head removed.

Referring now more particularly to the drawings, the numeral 5 designates an enclosing shell and on oppositesides thereof are the fluid receptacles 1 and 6, which are incorporated with theshell. The receptacles 1 and 6 are connected by means of the tubular coils 4 arranged side by side, and united to the receptacles by the unions 2. These coils are made of metal having good heat conducting properties and. suitable to the fluids to be used. In formation, the

coils are coiled from the center into the shape of a conical spiral, as shown in the figures. These coils are reversely spiralled from the center of the tubes of which they are formed, the two ends of the tube lying parallel and alongside approximately throughout their entire length so that the inlet and outlet ends will lie side by side and the mean temperature between the two ends of the coil will be the same throughout their length thus affording an even temperature throughout the cross section of the coil, The respective receptacles 1 and 6 have the inlet and outlet openings 7 and 8, respectively, and cold fluid may be admitted through the inlet 7 into the receptacle 6 and it will pass thence through the coils 4:

and into the receptacle 1 and out through the opening 8, thus cooling the coils.

The shell 5 has an inlet opening 10 through which the other fluid is introduced into the interior of the shell, usually in the form of vapor and under pressure, and the entering fluid is spread by the conical balile plate and distributed out through the shell and passes over and between the coils and it is suddenly chilled by them. Bafiie plates 11 are provided, which force the However, other suitable fastening means may be employed if desired The apparatus herein descried is particularly adapted for use in distilling oils, for extracting gasoline from gas and for other similar purposes.

What I claim is 1. A device of the character described, includingia shell, having an inlet and outlet opening, a fluid conducting tube within the shell formed into a conical shaped spiral, a i

pair of receptacles incorporated in the shell, the respective ends of said coil entering said receptacles, an inlet entering one receptacle, an outlet-entering the other receptacle, said coils being provided for the circulation of hot fluid therethrough to heat the fluid within the shell, and fluid collecting chambers formed within said shell.

2. A device of the character described, including a shell adapted to contain a fluid and provided with an inlet and a series of outlets, a series of coils within the shell, formed into a conical shaped spiral, a pair of receptacles incorporated into said shell, the respective ends of said conduit enter- .ing the corresponding receptacles, an inlet entering one of said receptacles, an outlet leading from the other receptacle, providing for the circulation of a heating fluid through said coils, fixed collective chambers formed p messes within the shell and each chamber having an within the shell which the respective ends 10 v inlet and an outlet. of said coil enter.

3. A device of the character described in- In testimony whereof I have signed my eluding a shell, a fluid conducting tube rename to this specification in the presence of versely coiled from its center into a general two subscribing witnesses.
